Instructions

  1. Preheat the oven to 350 degrees F. Lightly coat a 9 x 13-inch baking dish with cooking spray.
  2. Place the chicken in the baking dish. Layer the ham over the chicken. Layer the Jarlsberg over the chicken and ham.
  3. In a large saucepan, melt half of the butter over medium heat. Whisk in the flour to form a roux, being careful not to burn the mixture. When the roux is smooth, slowly whisk in the half-and-half. Switch to a wooden spoon and stir until the sauce is thick, about 5 minutes.
  4. Stir in the lemon juice, mustard, kosher salt, paprika, and white pepper.
  5. Bring the sauce to a low simmer, then remove from the heat.
  6. Pour the sauce over the casserole, making sure it covers all the corners.
  7. For the topping, melt the remaining butter in a medium microwaveable bowl. Stir in the panko, sea salt, and herbes de Provence. Sprinkle the mixture over the casserole.
  8. Bake for 45 minutes until the top is golden and the casserole is hot.
  9. Garnish with thyme and serve warm.
